Abstract (en)
[origin: EP0849905A2] In a CDMA multi-code transmitter in which data signals input from a plurality of data channels are spectrum-spread with mutually different spreading codes and resultant baseband signals are summed and transmitted, peak values of an eye-pattern is reduced to reduce power consumption by delaying the baseband signals before summed, such that transmission timings of the respective baseband signals are mutually shifted. <IMAGE>
